The Low-Tox GAPS Home: What We Actually Changed

Food is only one part of the GAPS changes we made at home. In Gut and Physiology Syndrome, Dr. Natasha Campbell-McBride includes drinking water, cleaning products, laundry and personal care in her discussion of reducing the body’s general toxic load.^[1] These were practical parts of our family’s changes too, alongside the meals.

Here’s what that’s actually looked like in our house: a laundry overhaul we made fast during an active eczema flare, a water filter we run every day, and a slow shift toward homemade skin care and cleaning products. None of it happened all at once, and none of it replaced the diet. It sits alongside it.

Why Your House Counts as Part of the Protocol

In the book’s explanation, reducing environmental exposures gives the body less to handle while the diet supports the gut and detoxification system.^[1] That is why the household recommendations sit alongside the food, rather than being a separate list of optional decorating ideas.

Dr. Natasha gives skin products particular attention. She uses medicines delivered through skin patches to explain why substances applied to skin deserve consideration, and connects that with her preference for simple edible ingredients.^[2] Her practical GAPS rule is the useful starting point here.

“If You Can’t Eat It, Don’t Put It on Your Skin”

Her general rule is: “if you cannot eat it, you cannot put it on your skin, scalp or teeth.”^[3] I use that ingredient filter when choosing homemade skin care. My family eczema story explains where the skin and laundry changes fit into our actual experience.

It’s a genuinely useful test, because it’s simple enough to run in a store aisle. Read the label. If you wouldn’t eat it off a spoon, GAPS’s position is that it doesn’t belong on your skin, your scalp, or your teeth either. That one line has quietly ruled out most of what used to be in our bathroom cabinet and under our kitchen sink.

Water: Why We Use a Berkey

The book recommends filtering water before drinking or cooking with it. It favors a simple carbon filter and advises against reverse osmosis and distilled water in its discussion of water’s energetic and biophysical properties.^[4] Those are the book’s recommendations; the filter we use in our house is a Berkey.

Our Berkey makes filtered drinking and cooking water part of the countertop routine. My water-filter comparison looks at the actual systems and product evidence, rather than treating the name of a filter as proof that it removes every possible contaminant.

Laundry: What We Changed During an Eczema Flare

Laundry matters in the book because residues remain in clothes, bedding and towels that stay against the body. Dr. Natasha recommends avoiding fragranced laundry products and looking for safer alternatives.^[5] Clothing and sheets were a major part of the changes we made during our third-born’s eczema episode.

Our third-born developed eczema for the first time in March 2026, at four, around the time our sixth child was born. We changed our laundry products, stopped using fabric softener and rewashed the clothes and sheets. We were also following Full GAPS, with a few meals out. Her skin cleared over five to six months. That was the combination of changes in our house, not a result I can assign to one product alone.

Dropping fabric softener and rewashing what touched her skin were part of that laundry overhaul. For routine laundry, I recommend the homemade direction described in my household guides.

Dishes: Homemade Dishwasher Detergent

Dr. Natasha recommends hand-washing dishes, particularly at the beginning of the program, with simple options such as mustard powder, vinegar or bicarbonate of soda. She gives detergent residue as the reason for preferring that approach to a dishwasher.^[4]

Homemade dishwasher detergent is one of the changes we use at home. I keep that family practice distinct from the book’s preference for hand-washing, so you can see both the recommendation and what our household actually does.

Skin Care: Homemade Lotions and Balms

The book recommends keeping personal care simple and reducing products applied to the skin. It names common shampoo, soap and toiletry ingredients in that discussion and gives edible oils, animal fats and plain washing as alternatives.^[2][6] My own preference is homemade lotions and balms with ingredients I can identify.

For a simple example, my body balm guide explains a beeswax-and-olive-oil preparation and its handling. For my hair care, I use homemade recipes from my books and Bumblebee Apothecary. I’m developing my own GAPS hair-care recipes, including options for curly hair.

Baths: The Aalgo Seaweed Swap

Aalgo seaweed baths are part of our household routine, and the children enjoy them. They fit the same edible-ingredient filter used throughout this article.

Where to Start if You’re Just Beginning

We did not replace everything in one week. The laundry changes happened during an active eczema episode, while other kitchen and household swaps came as our budget allowed. That is different from having every recipe and purchase settled before starting GAPS.

Start with one product you use often. You might remove fabric softener, work out your drinking-water setup or simplify a lotion. My course The Low-Tox GAPS Home and Low-Tox Home Swap Guide are listed in the WFLI Shop. The bath-routine article shows the separate book guidance and our own bath experience.

Frequently Asked Questions

Is Free-And-Clear Laundry Detergent GAPS Compliant?

“Free and clear” by itself does not tell you whether a detergent fits the GAPS approach. Our laundry change was a step we made during an eczema episode; my recommendation for routine use is homemade detergent. The book also discusses safer ecological alternatives, so commercial packaging alone is not its test of every product.^[1][5]

What Water Filter Does GAPS Recommend?

Dr. Natasha recommends a simple carbon filter and advises against reverse osmosis and distilled water in her discussion of water’s biophysical properties.^[4] A Berkey is the filter our family uses; it is not a claim that the book endorses a particular Berkey model.

Do I Need to Replace Everything in My House at Once?

No. Our kitchen and household changes came over time as money allowed. The laundry overhaul was one focused response during an eczema episode; it does not mean you need to replace every product before you can begin changing the food.

Can I Still Use Soap and Shampoo on GAPS?

GAPS’s own position is that plain water is enough for most washing, and that soaps, shower gels, and bubble baths add to your toxic load without much benefit. Where you do want a moisturizer, GAPS points toward edible oils and fats like coconut oil, olive oil, and tallow instead of conventional lotion.

Why Does GAPS Prefer Hand-Washing Dishes over a Dishwasher Machine?

The book’s reason is concern about detergent left on dishes. Dr. Natasha recommends hand-washing, particularly initially, using hot water and simple cleaning ingredients.^[4] Homemade dishwasher detergent is our own household practice, described above.
